1unn,citizen of thellnited States,residing at.

Chicago, in the count-y of Cook and State of Illinois, have invented certain new and useful Improvements in Feed-Points 'or friwls for Shoe-Sewing Machines; and do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to an im- .proved feed point or awl for shoe sewing machines and is designed primarily as an improvement on the feed pointjvhich has heretofore been used in the Well known Good-- year welt and turn shoe sewing machine. ln the Goodyear Welt and turn shoe sewing machine, above referred to, the feed point is formed integrally with a plate which is removably secured to the lower end of the feed point lever by bolts passing through theplate andthe lever.

The object of the present invention is to provide a feed' point .which can be more easily removed for sharpening than thefeed point which has heretofore been used, which is'less expensive? to replace when Worn out,

which can be used for a muchnlonger time before the substitution` of a nevv ,point is required, and which canbe readily adjusted so aszto engage the Work in the desired manner.

lilith the above objects in vievv the present invention1 consists in the `improved feed point' and the means for securing it to the feed point lever, hereinafter described and claimed.

The present invention Will be clearly understood from an inspection of the accompanyingdrawings in which Figure 1 is a View in side elevation, the cam shaft being shown in section, of a Good year Welt and turn shoe sev/ing machine with the present invention applied thereto. Fig. Q is a detail view in side elevation of the lower end of the' feed point lever-with the improved Vfeed point secured thereto. Fig.

is a View in front elevation of the parts illustrated in Eig. 2. "Figd is a detail sectional view takenon 'the line of Eig'. 2, and Fig. 5 is al view inside elevation of onecf the clamping plates by which the feed point is secured to the feed point lever, the bolt which passes through the slot in the plate.

being shown in section.`

TWith the exception of the vfeed point hereinafter described, the machine illustrated in Fig. 1 is substantially the same in all essential particulars as the machine illustrated and described' in the patent tol French and Meyer, No. 412,704, dated October 8, 1889,

1 indicating the curved hook needle, 2 the.'

needle guide, 3 the Ichannel guide, l the looper, 5 the take-up, 6 the thread-finger, and 7 the back rest.

In the illustrated embodiment of the pres.- ent invention the feed point is separate from the means by which it is secured to the feed point lever and preferably consists of a Wire 8 sharpened to a triangular point 9 at the oud which engages the Work. To secure the feed point to the feed point lever 10 two clamping plates 11 are provided, in the adjacent faces of.\v hich a groove 12 is formed to receive the shank of the feed point. The clamping1 plates 11 are secured to the lower end of the feed point lever by means of bolts. 18 and 14 which pass through the openings inthe plates and in the lower cnd of the lever. At one end the bolts 13 and 14 are provided With heads 15 and 16 which bear against the outer clamping plate 11 and at the other end the bolts are provided with screw-threads which are engaged by clamping nuts 17 and 1S. The bolts. 13 and 14 thus serve both to secure the clamping plates to the lever and to actuate the clamping plates to grip tli e feed point. j

lt is desirablein sewing machines of the class to which the present invention relates that means be provided whereby the feed point can be angularly adjusted to bring* it into the Vproper positionmfith relation to the needle. 'llo secure this result in thc Construction illustrated in the draivirue` the openings in the plates 11 through which the upper bolt 13 passes, elongated, as clearly shown in Figs. and 5, so that an angular adjustment of the. clamping plates and of the feed point, about the axis of the lower bolty 14. is permitted.

it Will be noted that in the construction illustrated in the drawing both clamping,r bolts are actuated by means of similar nuts and that these nuts are upon the same side of the lever l() Where they. are readily accessible. To enable the nuts to be readily turned when it is desired to either loosen or tighten the clamping plates, he portion of the bolt 13 which passes through the slots in 1 the plates l1, is squared, so that the bolt is held from turning, and the head of the bolt 14 is provided with a pin Which enters a hole in the outer plate 11 so that the bolt 14 is also prevented from turning.

By loosening the nut- 1-7 on the upper bolt 13 the clamping plates can be angularly adjusted to bring the feed point into the desired position with relation to the needle, and by loosening both nuts 17 and 18 the feed point can either be removed for sharpening or can be adjusted longitudinally. Neither the angular adjustmentor the longitudinal adjustment of the feed point, or its complete removal, necessitates removing the clamping pla-tes from the machine so that the desired adjustments can be made or the feedpoint removed, sharpened and replaced Wit-h very little trouble. 'The feed pointl is extremely durable and Will last for a long period of time since the Wearing awa-y ofthe point by grinding can be compensated for by adjusting the feed point longitudinally. 4

The invention having been thus described, what is claimed is 1. A shoe sewing machine, having, in combination, a feed point, a feed point lever,- clamping plates engaging the feed point constructed to permit a longitudinal adjustment of the feed point, and means for securthe plates to the lever While permitting an angular adjustment of the plates.

2. A shoe sewing machine, having, in combin-ation, 'a feed point, a feed point lever, clamping plates receiving the feed point'between them, and bolts for actuating the clamping plates and for seeuring said plates to the feed, point lever passing through openings in the plates and. lever and held from rotation bythe plates.

3. A shoe sewing machin-e, having, in combination, a feed point, a feed point lever, clamping plates engaging the feed point, a clamping bolt about which the plates are angularly adjustable passing through the plates and lever, and a bolt for securing the plates in adjusted position rigid With'relation to the lever.

4. A shoe sewing machine, having, in Combination, a feed point, a feed point lever, clamping plates receiving the feed point between them, and clamping' bolts passing through the clan'xping plates and lever and serving both to actuate the clamping plates and to secure said plates to the lever.

A shoe sewing machine, having,`in com;

bination, a feed point, a feed point` lever,`

clamping plates engaging the feed point, and means for securing 'the plates to the lever while 'permitting an angular adjustment of the plates, comprising a bolt passing through slots in the plates and through the lever and held from rotation by said slots.
